AG - Autogenous & SAG Semi-Autogenous Mill Design …

Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp; Speed reducer efficiency: 98%; 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power). Therefore select a mill to draw at least 5440 Hp at the pinionshaft. Based upon the pilot plant test results, the volumetric loading for the mill can be determined.

SAG Mill Grinding Circuit Design - Mineral Processing

As mill sizes increases, the required volumetric capacity of the pulp lifters grows proportionally to mill volume. Since AG/SAG mill volume is roughly proportional to the mill radius cubed (at typical mill lengths) while the available cross-sectional area grow's only as the radius squared, pulp lifters must become more efficient at transferring slurry in larger mills.

Effect of Mill Filling on the Energy Input. The effect of mill filling on the energy input is studied by varying the number of discs. Figure 6 shows the variation of torque with mill filling. Mill filling is calculated based on the fraction of the total area occupied by the discs. As expected, the energy input reaches a maximum and then falls off.
